tests: remove internal refactoring entry + snapshots

why: Refactoring had no user-visible behavior changes; update test snapshots for new explicit ./ workspace tests.
what:
- Remove CHANGES entry about internal legacy heuristics cleanup
- Add snapshots for path-explicit-dot-workspace tests

refs: Internal cleanup
